Both cross-sectional comparisons and patterns of change in productive activities among members of the MacArthur Successful Aging cohort were examined. The data came from a three-site longitudinal study of community-dwelling adults aged 70-79. The highest functioning cohort (n = 1,192) was found to be significantly more productive than a comparison group of medium- and low-functioning respondents at baseline in four of five domains examined. In longitudinal models, we tested several hypotheses regarding the determinants of change in levels of productive activity over a three-year period. Overall, 15.1 percent (n = 162) of the cohort became less productive, while another 12.7 percent (n = 136) became more productive. Risk factors for decline in productivity included hospital admission and stroke. Age, functional disability, marriage, and increased mastery were protective against declines. Conversely, Blacks, those who were more satisfied with life at baseline, and those reporting increased mastery were more likely to increase their productivity.
